Sounds like you should be able to get around 500Mhash/s on the 7970 not sure of those are overclocked also though.
Make sure you have the current drivers installed and the AMD APK thing installed. I'm using reaper to mine. Mess with the aggression settings to speed up or slow down mining speed. This is going to cause havoc to your screen if it's set too low and may even lock up. Try using multiple threads per GPU also.

Thanks for that i love reaper but its messing me around with the 7970 can not get it to work always getting the error 6 im happy with the 7870 but a lot of people are claiming 700 from the 7970 on cgminer but every time i load it goes crazy with both cards as i have still not figured out how to set it up for 2.
